Improvement in printing-presses



CHARLES CAMILLE MAURICE, 0E NEW YORK, N. Y.

IMPROVEMENT IN PRINTING-PRESSES.

`Specilication forming part of Letters Patent No. 103,351, dated May 24,1870.

To all whom it may concern:

Be it known thatI, CHARLES CAMILLE MAURICE, of the city, county, andState of New York, have invented a new and Improved Printing-Machine;and I do hereby declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the art to makeand use the same, reference being had to the accompanying drawings,forming part of this specification, inwhich- Figure lirepresents a sideelevation, partly in section, of. my improved printing-machine. Fig. 2is an end elevation of the same.

Similar letters of reference indicate corresponding parts.

This invention relatesto a new machine which can be employed for allkind of lithographic and autographic printing, and also printing withtypes.

The invention consists, chieiiy, in the employment of a stationarysegmental platen, in con j unetion with a cylindrical printing-roller,whereby more rapid and satisfactory operation can be produced.

The invention consists, also, in the arrange ment of mechanism for`operating the said roller, as hereinafter more fully described.

A in the drawing represents the frame of my improved printing-machine.The same supports the stationary printing block or platen B, which hasits printing-surface a curved, as shown. The curve of the surface a isdescribed from the axis of a shaft, C, as center, the said shaft beinghung in the lower part of the frame A, as shown. However, the curve maybe slightly varied. D is a lever projecting from the shaft C. Upon thesegmental stone B is used a roller, E, which is made of stone or othersuitable material, and which is provided with projecting axles d d, asshown. The length ofthe roller is about equal to the width of the stoneB. When the roller is used its axle ends are fitted under hooks b b,that are formed on bars F, which project from the lever D.

A spring, G, may, if desired, be used to throw the free end of the leverup and carry the roller to the higher part of the stone B.

The printing may either be done hy the roller or by the block B, orboth. In the latter case both sides of one sheet can at once be printed.

The operation isas follows: When the roller is used for printing, it istaken off the block B, wetted, and inked on suitable cushions, and thenput under the hooks b and rolled. over the paper, which has in themeantime been placed upon the curved surface of the block B. If

the latter is also used for printing, it is Wetted and inked beforereceiving the paper.

Should the invention be used for type-printing, the wetting will bedispensed with.

The roller is moved over the stone both by direct action and also by theapplication o weight to the fr'ee end of the lever.

The arms F swing on an independent pivo on the lever D, and as thelatter turns on its fulcrum C while the roller moves over the block, thepivots of F will be ca-rried down, and pressure consequently applied tothe matter between the block and the roller. The spring serves toelevate the lever and carry the roller up after a sheet has beenprinted.

It is evident that the block B may be made of stone, metal, or othersuitable material.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The curved stationary block B, having curvedprinting surface, combined with a printing-roller, E, as and for thepurpose described.

2. The shaft d and arms F F, combined with a lever, D, and spring G,connected together to move the roller E backward and forward.
